    Abstract: Different Pyrazoline derivatives were synthesized by cyclization of substituted chalcone derivatives in presence of hydrazine hydrate. A series of novel 1,3,5-triaryl pyrazoline derivatives has been synthesized by the reaction of chalcone and phenylhydrazine in the presence of Silica-supported Preyssler Nanoparticles, H14[NaP5W30O110]/SiO2, Preyssl...
